VALVE.

SPECIFICATION forming partof Letters Patent No. 658,975, dated October2, 1900.

Application filed July 30, 1900. Serial No. 25.229. (No model.)

T0 on whom it may concern.-

Be it known that-I, THOMAS OLANoY, acitizen of the United States,residing at Bridgeport, county of Fairfield, State of Connecticut, haveinvented a new and useful Valve, of which the following is aspecification.

My invention has for its object to provide a valve which shall beadapted for general use, and especially adapted for use asahot-waterradiator valve, my novel valve being durable,

practically impossible to get out of repair,

easily and quickly operated to open and close, attractive in appearance,and consisting of but few parts and those easy to make, so that my novelvalve,while superiorin operation to other valves of the class now in themarket, is cheaper to make and can be placed upon the market at a lowerprice than any other valve of its class.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of my novel valve complete, the cover or valveproper being in the closing position; Fig. 2, a similar view,the cap,lever, and spindle being removed; Fig. 3, a section of the body andvalve proper on the line 3 3 in Fig. 4, thevalve being in' a partly-openposition; Fig. 4, a section on the line 4 4 in Fig. 3; Fig. 5, aperspective of the cover or valve proper and the inner end of thespindle detached; Fig. 6, a perspective of the spring detached, and Fig.7 is a perspective of a slightly-modified form in which the spindle maybe made integral with the cover or valve and no spring is used.

A denotes the body; B, the hub; C, the inlet or pipe end; D, the outletor union end; E, the cover or valve proper, which is arc-shaped andoscillates in the body; F, the spindle; G, the leveror operating device;H, the packing nut, and J the cap.

The interior of the body is cylindrical,preferably ground smooth, isopen at one end, and is provided with an inlet-opening 10 and anoutlet-opening 11. These openings are adapted to be either wholly orpartially covered or closed alternately by the arc-shaped cover or valveproper,E. This cover or valve is provided with arms 12 and 13, said arm13 being provided with'an opening 14, adapted threads,as at 21.

to receive a stud 15, which is cast upon or rigidly secured to the bodyat the center of the inner end thereof, and arm 12 being provided withan angular opening 16, adapted to receive an angular lug 17 upon thespindle F. I have shown the spindle as provided with a hub 18, whichlies in a socket 19 in the inner face of the cap.

K denotes a bow spring, the ends of which engage stud 15 and the innerend of the spindle, respectively, and which bears against the inner sideof the valve and holds it pressed tightly against the inner periphery ofthe body, said inner periphery of the body constituting the valve-seatand being indicated by 20.

23 denotes stops which may be placed either upon the inner end of thebody or upon the cap to limit the oscillation of the valve in eitherdirection;

The mode of assembling my novel valve will be readily understood fromFig. 3. The cover or valve proper, with the spring lying therein and thelug upon the spindle in engagement with opening 16,is passed in at theopen end of the body, stud 15 at the inner end of the body engaging hole14 in arm 13 of the valve. The cap J is then turned to place, the openend of the body and the cap being provided with corresponding screw-After the above-mentioned parts are all in place lever D maybe securedto the spindle by means of a screw 22.

In the form illustrated in Fig. 7 the spring is omitted, the cover orvalve proper is cast integral with or is rigidly secured to the spindle,and the hole 14 in the spindle is made to closely engage stud 15 uponthe inner end of the body,so that the valve will fit closely enough inplace for many uses-for example, in hot-water radiators,in which, if thevalve engages the seat too closely, it is common to make a small openingthrough the valve in order to prevent entire stoppage of circulation.

Having thus described my invention, I claim- 1. The combination with acylindrical valve-body having inlet and outlet openings and a stud 15 atits inner end, of an oscillavalve-body having inlet and outlet openings,of an oscillatory arc-shaped valve adapted to close either of saidopenings and a bow spring whose ends have bearings at the ends of thevalve and which bears against the inner side of the valve to hold itpressed against the inner periphery of the body.

In testimony whereof I aifix my signature in presence of two witnesses.
